A default disposal chain defines a standardized logistical disposal concept. It defines the number of stages and the processes carried out at each stage and the transport processes, such as loading and unloading processes. In addition, the category of the means of transport - route train, forklift or AGV - is selected there and it is determined whether there is an empties transport.
The following basic functions are available in the Default Disposal Chain Editor sub-module:
- Adding a new standard disposal chain
- Renaming a newly created/existing standard disposal chain
- Duplicate a standard disposal chain. The original standard disposal chain is copied 1:1. The processes and stages are arranged in the same way.
- Delete a standard disposal chain.
If for some reason the wrong standard disposal chain has been deleted, it can be restored. This is only possible if the sub-module has not been saved between saving and restoring a standard disposal chain.
Creating a default disposal chain
When you create a default disposal chain, the display is as follows:
|1||Adding a new stage process|
|2||Deleting a stage|
|3||Selection of the transport container - either load carrier or load unit|
|5||Selection of the type of transport - For direct transports incl. direct means of transport and, if necessary, workers|
Consideration of distribution times
To the stages (1):
A layout level must be defined for each level. This is selected using the layout levels defined in the layout structure in the Layout Editor sub-module (see screenshot). For the first level of the default disposal chains, the layout level of the last level of the corresponding default supply chains is always used.
To the transport containers (3):
Two different transport containers - load carriers and load units - are currently available to the user.
The input type of the transport container on the following level is always defined by the output type of the transport container on the preceding level. In this example, the output container at the set level is a loading carrier, since a loading carrier is also transported from the warehouse t to the set.
To the transports (4):
There are two different types of transport selection. Route stands for a transport with the route train, always consisting of tugger and trailer.
However, if the transport is carried out with a forklift or AGV, the term Direct must be defined in the ComboBox.
As soon as this selection has been made, the previously red area appears green.
In the case of direct means of transport, this must be selected. In the case of transport with a forklift, the selection of the worker for the means of transport is also mandatory.
The values defined in the default disposal chain for workers and direct means of transport are transferred directly from the default process chain to the supply chain editor. There, values for the direct means of transport and, if necessary, the worker can be manually adjusted again.
For the processes (5):
Stage processes must be defined for each stage. The worker and the process must always be entered as soon as a stage process has been added. A worker can also be assigned several processes. Several workers can also carry out different or the same processes on one level.
The loading and unloading processes that took place before or after a transport between source and sink are defined in the same way as the stage processes. However, no direct assignment of a worker is possible.
The data for selecting the workers and the percentages for calculating the distribution times come from resource management, the process names and times from process element management.
|Process time||Net process time|
|Allowance||Buffer times --> total allowance [%] * net process time|
|Total time||Process time + allowance|
When a default disposal chain is deleted, it must be saved in order to apply the changes. If only the default disposal chain is deleted via the Delete button, the change can be undone via Discard.
Defining a default disposal chain for a default supply chain
A default disposal chain can be defined for each level of the existing default supply chains. This is only possible if default disposal chains have also been created and fully defined. However, you can still create default supply chains without defined default disposal chains. You can also undo the assignment of a default disposal chain to a default supply chain.
First the desired default supply chain must be selected from the table. The selected chain is highlighted in blue.
The fields highlighted in yellow can be used to select and save the respective default disposal chain for each level.
Each selected default disposal chain can also be deleted, so that none is selected anymore.The default disposal chainsassigned here can then also be seen in the supply chain editor.
